[Seaside] Next Seaside 2.8 overrides

[Pavel Krivanek]

Hi,

The are some next overrides in Seaside 2.8. This overrides aren't in
kernel packages but they are in the minimal set of packages required
by Seaside.

1)
!JPEGReadWriter2 methodsFor: '*seaside2-squeak' stamp: 'mb 6/12/2006 13:58'!
nextPutImage: aForm quality: quality progressiveJPEG: progressiveFlag

it seems that the Squeak 3.9 contains the same code

2)
!HttpRequest methodsFor: '*seaside2-squeak' stamp: 'dc 11/5/2006 21:45'!
parseCookies: aString

Seaside can be fully independent without this overrides (at least in
the KernelImage)

Cheers,
